Regional variation and the effect of lake: river area on sex distribution of American eels
Silver phase American eels, Anguilla rostrata, were collected while migrating from five rivers in Maine, U.S.A. Sex ratios varied from 49 to 98% male for these rivers and had a range of 46% over a 30 km distance between the mouths of three rivers. The proportion of male eels was inversely related to...

Sex ratios varied from 49 to 98% male for these rivers and had a range of 46% over a 30 km distance between the mouths of three rivers. The proportion of male eels was inversely related to the amount of lacustrine habitat in the five drainage areas (r=−0·95, P=0·014). A combination of these sex ratios and published data from two Nova Scotia rivers showed large variation in the proportion of male eels within 1° of latitude. Thus, the hypothesis from the literature that the distribution of the sexes is dependent upon distance of larval transport was not supported. Eels migrating from lacustrine habitats within a river were predominately female, while eels migrating from fluvial habitats were predominately male, regardless of upstream distance. Apparently river habitat influences the distribution of the sexes and may play a role in sex determination. | ||

Regional variation and the effect of lake: river area on sex distribution of American eels |
| abstract |
Silver phase American eels, Anguilla rostrata, were collected while migrating from five rivers in Maine, U.S.A. Sex ratios varied from 49 to 98% male for these rivers and had a range of 46% over a 30 km distance between the mouths of three rivers. The proportion of male eels was inversely related to the amount of lacustrine habitat in the five drainage areas (r=−0·95, P=0·014). A combination of these sex ratios and published data from two Nova Scotia rivers showed large variation in the proportion of male eels within 1° of latitude. Thus, the hypothesis from the literature that the distribution of the sexes is dependent upon distance of larval transport was not supported. Eels migrating from lacustrine habitats within a river were predominately female, while eels migrating from fluvial habitats were predominately male, regardless of upstream distance. Apparently river habitat influences the distribution of the sexes and may play a role in sex determination. |

Silver phase American eels, Anguilla rostrata, were collected while migrating from five rivers in Maine, U.S.A. Sex ratios varied from 49 to 98% male for these rivers and had a range of 46% over a 30 km distance between the mouths of three rivers. The proportion of male eels was inversely related to the amount of lacustrine habitat in the five drainage areas (r=−0·95, P=0·014). A combination of these sex ratios and published data from two Nova Scotia rivers showed large variation in the proportion of male eels within 1° of latitude. Thus, the hypothesis from the literature that the distribution of the sexes is dependent upon distance of larval transport was not supported. Eels migrating from lacustrine habitats within a river were predominately female, while eels migrating from fluvial habitats were predominately male, regardless of upstream distance. Apparently river habitat influences the distribution of the sexes and may play a role in sex determination. |
